not sure if my hybrid got it from laying on the rocks at that angle or from the resent mini cycle but it has it now. i took all the rocks out so it can't rest on them to help straighten it out with the aid of gravity. has anyone seen it get reversed before? i haven't seen it bent for long maybe a few days that i notice it after taking the rocks out. now i have the tank more open and rock free so hopefully it will go away with clean water and open spaces.
